Optional or not the more new and different things they include the more I have to pick and choose from when it comes game time. I know that there are bound to be changes that I will not like and that I'll probably go back to the original 3e for, so I'm all for a whole lot of change. Like I said in another thread if the changes aren't extreme enough I simply will not by the book, I'm not paying for the same material twice just to have the newest edition. I'm not required to buy it, and if they don't make it worth my while I'm not going to.
